Here and there along winter shorelines, little flocks of pale, silvery shorebirds probe at the water’s edge, keeping pace with each wave’s ebb and flow. These are Sanderlings, small sandpipers that stay through the winter. Rachel Carson, in Under the Sea Wind, described Sanderlings as running “with a twinkle of black feet.”  Learn more about the Sanderling at Cornell's AllAboutBirds, and listen to BirdNote this Saturday morning before the 9 o'clock news on VPR.
